Abstract : New rate measurements of the flow of the saturated helium film out of a Pyrex beaker, employing a capacitance depth gauge technique, have been obtained. The high resolution has allowed one to observe the occurrence of transitions as small as 1 1/2% of the flow rate. Such transitions are much smaller than any previously observed or expected from earlier measurements, which resulted in a preferred flow-rate hypothesis. Even so, the results do establish that some form of a preferred flow-rate structure is a fundamental feature of helium-film transport. (Author)
